Specification forming part of Leiters Patent No. 165,181, dated July 6,1875,

To all whom t may concern.:

Be it known that I, EDMUND RUSSELL, of Brooklyn, Kings county, New York,have invented a certain Improvement in Radiators, of which the followingis a specification:

My invention relates to radiators composed of groups of U or loop pipes,connected to a common steam-chest; and it consists in introducingbetween such loop-pipes, or in winding around them, coils of metallicWire or perforated sheets of metal, which are heated by contact with thepipes, and which thus enlarge the area of heated surface, against whichcurrents of air are brought into contact in passing through the chamberor passagel in which the group of radiators is placed.

The accompanying drawings are as follows:

Figure l is an end View of two series of my loop-pipe radiators, affixedto the alternatelyinclined passages or bends of my steam-chest. Fig. 2is a Vertical section of the same through the line x x on Fig. 1. Fig. 3is a top view;

and Fig. 4 represents my perforated sheet of posite directions, andwhich are arranged one application filed above the other. Aftixed to theside of each one of these bends are the U or loop pipes b b, which arealso slightlyinclined, so that the mouth of each loop-pipe is slightlylower `than the outer end, where the two legs are in the ordinary way.

I claim as my invention- '1. In combination with a group of loop-piperadiators, arranged in relation to each other substantially as shown anddescribed, coils of metallic wire introduced between the looppipes. asIand for the purpose specified.

2. In combination with a group of loop-pipe radiators, a coiled sheet ofperforated metal, substantially as shown and described.

3. In combination 'with a loop-pipe radiator,`

a coil of metallic wire wound around the loop pipe, as and for thepurpose specified.
